edit configuration.

sudo gedit /etc/ld.so.conf.d/opencv.conf

Add the following line at the end of the file(it may be an empty file, that is ok) and then save it:

/usr/local/lib

configurate lib

sudo ldconfig

sudo gedit /etc/bash.bashrc # or /etc/zshrc if its zsh

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH

if you're using virtualenv, copy from your python dist directory

cd /usr/local/lib/python2.7/dist-packages/ sudo cp cv2.so ~/.virtualenvs/the_virtualenv_name/lib/python2.7/site-packages/ sudo cp cv.py ~/.virtualenvs/the_virtualenv_name/lib/python2.7/site-packages/ sudo cp cv.pyc ~/.virtualenvs/the_virtualenv_name/lib/python2.7/site-packages/
